⚠️ Fluent Bit, a widely deployed telemetry agent, has multiple critical vulnerabilities disclosed by Oligo Security affecting inputs, tag processing and output handling. Patches are available in Fluent Bit v4.1.1 and v4.0.12 released in early October 2025; older releases remain at risk. Operators are advised to update immediately, avoid dynamic tags, lock down output file parameters, run with least privilege and mount configuration directories read-only to reduce exposure.
